We met Kenin in 2012 when he visited ZCG with his Infiniti G37 IPL. After working on the G, years passed by and Kenin reached out to us having purchased a 2018 Infiniti Q50S sedan. He saw that we were working with other customer’s Q50s and asked if we would be down to tune his. We happily obliged, especially since Kenin’s Q50 was rear-wheel-drive.
Straight from the factory, the VR30DDTT is an impressive motor. The Hi-Output version is rated at 400 hp and 350 ft-lbs tq, underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Kenin’ Q received several parts from AMS Performance including their AMS Heat Exchanger, AMS Coolant expansion tank and AMS Air intakes. We also intalled his strut tower brace:
The new heat exchanger compared to the stock unit and installation:
AMS air intakes compared to OEM:
AMS expansion tanks compared to OEM:

Rob was eager to tune the Q using Ecutek. Baseline power was 359hp/374tq at the wheels. With the AMS parts and tuning final numbers were 400hp/449tq, gains of +41hp/75tq:
Enjoy the Boost Kenin!
Special thanks to Seb at SpecialtyZ for helping us!
Glenn is an avid Datsun enthusiast having owned and raced several cars. You might remember his VIPS 240z vintage race car from the Rolex Monterey Motorsports Reunion last year where he ran it alongside our hero John Morton. We also dyno-tuned the Z in preparation for race week. Look for #39 at this year’s RMMR!
Taz is a veteran Datsun racer, having completed the Carrera Panamericana in both a 240z and 510, built by our friend Troy Ermish. You might find the #51 510 familiar as the previous owner was Wayne McAttee!
Like all race cars that get dyno’d at ZCG, these 510s left with more power and peace of mind! Enjoy the dyno video below and listen to the L-series sing!

Glenn loves his vintage race cars and he recently added this B-sedan Datsun 510 to his stable. He plans to race it this year with SVRA, and it also got accepted to the 2018 RMMR event!
In preparation for the upcoming RMMR, Glenn visited Z Car Garage to have the B-sedan dialed-in with chassis dyno tuning.
Chassis dyno tuning is extremely beneficial for race cars. You simply can’t run your race car up and down a city street to emulate race conditions and “guess” how your engine settings are performing. In most cases our customers have their engines built and tested on an engine dyno, so it is prudent to confirm performance on the chassis dyno before heading out to the track.
We run a series of dyno tests for the customer, including fully heat soaking the engine to ensure it can perform throughout the rev range. Glenn’s 510 was optimized for drivability in his desired powerband and like all race cars that get dyno’d at ZCG, his 510 left with more hp/tq! Enjoy the video of a few dyno pulls and listen to that L-series sing:
We can’t share numbers as racers like to keep them close to their heart, but you can count on the 510 being ready to rock in the B-sedan group at big race. Thanks for letting us tune your Datsun, Glenn!
Scott visited Z Car Garage for dyno tuning of his Datsun 510. He had the engine installed by our friend Troy Ermish and wanted Rob to perform the final tune/sorting.
When you have a shop perform an engine install it is critical to have it tuned and confirm power/drivability.
On the dyno baseline numbers were 129hp/129tq at the wheels. With tuning we picked up 11 hp and 9lb-ft of torque for a total of 140hp/138tq to the wheels:
Scott is coming back to ZCG next month to get a larger exhaust installed as the stock exhaust is definitely limiting output.
Jason S had his 2012 370z supercharged at a performance shop in the Sacramento area. He then tracked us down to install a smaller pulley and raise the boost level followed by UPREV tuning to replace the base CAN tune.
Once we got his car into the shop we realiZed there were several things to handle before increasing the power. First, it is important to put in a colder spark plug in a car with forced induction and we used our proven GT-R units. When going from 280whp to 400whp we wanted to make sure nothing was rubbing so the following items were addressed:
All vacuum and boost lines were secured to keep them from popping off:
We corrected wiring at the ART pipes where a wire was touching the exhaust:
We corrected orientation of MAF housing:
The oil cooler lines were secured to prevent from rubbing anything on the front end:
We rectified the flaky wiring to the intercooler pump that allows water to flow into the cooler. No more on/off issues with the pump. With all of the clean-up work sorted we installed the smaller supercharger pulley and UPREV tuned the Z:
ZCG has performed many Stillen s/c kits and it’s a wonderful way to pump up your Z with minimal hassle and great power gains. Thank you Jason for letting us sort out your Z!
